Arithmetic function block modes
Value range
The function block operates in the integer range from
–2147483648 to +2147483647.
Behaviour when value range is exceeded
• The function block sets the switching contact AR..CY to
status 1.
• The function block retains the value of the last valid
operation. The value is zero when it is first called.

Contacts
AR01CY to AR32CY: CARRY overflow bit, value on function
block output greater than or less than the value range.
AR01ZE to AR32ZE: zero bit ZERO, value at the function
block output equals zero
Coils
The arithmetic function block does not have any coils.
Memory requirement of the arithmetic function block
The arithmetic function block requires 40 bytes of memory
plus 4 bytes per constant on the function block inputs.
